v SHEET HOLDER.

I Application filed March 4., 1924. Serial No. 696,879.

The objects of my invention are to provide means adapted to enable theuser of hold the same; to provide means adapted to enable a user of thedevice to quickly install thereon and remove therefrom the materialintended for use; and to provide a sheet holder adapted to minimize thewaste of such materials as may be used thereon.

My invention consists in providing a block having rounded ends andhaving a clasp secured adjacent each of said ends and on top of saidblock; in providing conveniently operated clasps each of which comprisesa pair of spaced apart pointed pins extending outwardly andlongitudinally of said block and having their ends adjacent one of saidrounded ends; in providing a metal base plate between said pinsandcombinedly fixed to said pins and said block; in providing a clampingframe comprising a pair of spaced apart rods extending longitudinally ofsaid block and slightly curved outwardly and having their inner andouter ends bent inwardly and connected with spaced apart in-v ner andouter rods integral therewith and extending transversely of said blockand means for linking said inner transverse rod of said frame with theinner ends of said pins; in providing a metal band connecting saidlongitudinal rods and slidablethereon and means for securing said claspin closed position comprising an outwardly extending lug having an earintegral therewith and extending at right angles thereto, said lug fixedto said base plate and adapted to be engaged by said metal band.

My invention further consists in the parts and in the combination andarrangement of p t a herein Set f rth an cl im d.

In the preferred construction of my invention as illustrated I provideblock 1 having rounded ends 1. At each end of the block is fixed abuckle or clasp 2 having a pair of equal distanced spaced apart pins 3extending longitudinally of. said block and having points 4 projectingoutwardly. The pins are secured in position bybase plate 5 having ends 6bentthere-around and secured to the block by screws 7. For securelymaintaining the pinsagainst movement relative to plate 5 I prefer tosolder them to the plate.

Clamping frame 8 has spaced apart rods 9. curved outwardly from block 1and extending longitudinally thereof and has inner and outer ends 10 and11, respectively, bent downwardly and slightly inwardly. Rods 13 and 14integral. with rods 9, respectively, connect ends 10-10 and 11-11 andextend transversely of block 1.

by forming the clamping frame from a single bar. Inner end 13 has lungedcon- 18, respectively, bent around inner rod 13 of clamping frame 8 andconnecting nection with rod15 extending transversely with rounded end lof block 1.

21 is then slid longitudinally inwardly and &

pins 3 may have suitable length for providing proper adjustment of outerrod 14 relative to points 4 of pins 3 when clasp 2 is in closedposition.

Base plate 5 also has integral therewith lug 19 extending outwardly andhaving car 20 bent at right angles thereto and extending outwardly forthe purpose of engaging metal band 21 looped around and connect inglongitudinal rods 9 thereby maintaining the clasp in closed position asshown in Figs. 1, 2, 3, 6 and 10.

Longitudinal rods 9 are curved outwardly to provide sufficient spring inclamping I frame 8 for the purpose of retaining outer 7 rod 14 intension engagement with points 4 when the clamp is in, closed position.

The operation of the mechanism of my in vention is as follows:

Assume the clasp is in open position as shown in Fig. 1 and that it isdesired to securea shoe polishing cloth thereto. One end 22 of cloth 23is pierced by ends 4 of pins 3 whereafter clamping frame 8 is closed byfirst lowering outer rod 1 1 downwardly and in engagement with the clothand beneath points at of the pins. Inner rod 13 of the clasp is thenlowered in engagement with the block whereupon the lever action ofconnecting plate 16 connected to inner rod 13 integral with frame 8' androd 15 integral with the inner endof pins 3, causes.

outer I'Od 14c of frame 8 to tightly grip the cloth and hold it securelyin engagement Metal band in engagementwith' ear 20 of lug 19 the shyretaining inner rod 13 of the clasp against upward movement and lockingthe clasp in closed position, as shown in Fig. 10. The other end 24 ofthe strip of cloth 23 is then tightly drawn around the under side 25 ofblock 1 andplaced in position in the clasp fixed to the other end of theblock by the same method asemployed' for securing end 22 mths clasp asdescribed.

I have, therefore, invented an extremely.

simple, efficient, efiective economical: and serviceable device for thepurposes intended;

An advantage of'my invention is; that a layer of cloth, sand paper orother similar material may be clamped thereon and the complete stripexcepting the small portions at the end in engagement with the clasp maybe utilized without waste. 7

The usual method of manually sanding surfaces is to place a strip ofsand paper upon a rectangular block and hold the sides or ends of thesand paper against the sides of the block by. the use of the thumb andfingers. This operation is not only verytiresome but. also involvesconsiderable waste of sand paper inasmuch as it is im possible to retainthe. paper in close contact with the block and when sanding the surfacethe and paper sometimes becomes crumpled and broken thereby renderingthe same unfit for use as well as producing a marred or rough surface onthe article being sanded. It is then usually necessary to discard thestrip of sand paper and substitute therefor a new piece.

By the use of my sheet holder many 1naterials may be securely held inposition for various purposes. I

Another advantage of my invention is that my clasp is so constructedthat it will securely retain materials of various width and withoutregard to the width of the clasp itself. v

My invention is capable of some modification without departing from itsscope or spirit as defined in the claims.

VVhatI claim as new and desire to secure by Letters Patent is:'

1. In a sheet holder, a block having ends, a clasp fixed to the top andadjacent an end of said block, said clasp comprising a pair of spacedapart pins extending longitudinally of saidblock and having their innerends connected with a rod extending transversely of said block, a baseplate intermediate said pins and fixed thereto and fixed to saidblock, aclamping frame having itsends bent downwardly and having its inner endlinked to said rod, the opposite end'of said frame adapted to beretained under said pins when in clamping position andmeans for holdingthe frame in closed or clamping position.
